MiniLyrics is a small plugin for a variety of different music players. The service displays lyrics to your favorite songs whilst they are playing. The
MiniLyrics database is large enough to cover most people's music tastes, and once set-up, the plugin runs when you open your media player of choice.
MiniLyrics has support for numerous media players including iTunes, Winamp and Windows Media Player.

Key features include:

Numerous media player supported.

Automatically search and download lyrics.

Overall MiniLyrics is great little tool if you are really into your music. The support for different media players is good and the lyric library is extensive. You can even save downloaded lyrics for tracks to be viewed/listened to offline. The downside is although MiniLyrics is free, you are faced with some annoying registration reminders.
